You know what, I’ll explain what her eyes are meant to look like. We don’t get that explanation for many years ( http://wapsisquare.com/comic/lunch-buddy/ ) and the medium doesn’t do them justice, so I don’t think it’s a spoiler to explain what you’re meant to be seeing.

She “a combination of six people”, and her irises (presumably black or other dark colour) fill her entire eye sockets; her eyes have no white to them. Whether or not she has multiple pupils (possibly represented by the white highlights?) is not clear. People have mocked her by calling her “spider eyes” before.
